Enorme crater explica le disparition del dinosaurios.

(Languages: Interlingua, English)

SUA: Le cadita del meteoro que causava le extinction del dinosaurios ante 65 milliones annos creava un crater si grande como Belgica. Isto es usque dece vices plus grande que antea prediceva le expertos. Le revista "Science" reporta nove investigationes al presumite loco ubi cadeva le meteoro, le peninsula Yucatán in Mexico. Iste crater, que previemente esseva estimate a haber un diametro de 175 km (cento septanta cinque kilometros), es 300 km (tres centos kilometros), secundo nove analyses, quasi tan grande como Belgica.

Isto face plus credibile le theoria del sequente undas fluvial, eruptiones vulcanic, incendios de forestes, e dramatic cambios climatic que occideva le dinosaurios. Le crater Chicxulub es le plus grande del interne systema solar.

Le crater esseva discoperite solmente ante dece annos proque illo esseva plenate de depositos de petras de calce. Virgil Sharpton, scientista al Instituto Lunar e Planetari in Houston, Texas, pensa que le crater esseva create per un explosion que equivaleva a 100-300 (inter cento e tres centos) milliones de megatonnas de TNT.

Ille estima que le explosion jectava a in le atmosphera 200.000 (duo centos mille) kilometros cubic del terra con le qual illo collideva, que causava le disapparentia del sol pro plure menses. Isto debe haber create un breve etate glacial, que eradicava le dinosauros.

Le theoria de iste grande catastrophe esseva publicate in 1980 ma non esseva universalmente acceptate proque nemo habeva detegite un crater de un grandor que possibilemente poterea explicar un catastrophe del natura tan grande.


An enormous crate explains the disappearance of the dinosaurs.

USA: The fall of the meteor that caused the extinction of the dinosaurs sixty-five million years ago created a crater as large as Belgium. This is up to ten times larger than experts predicted earlier.

The magazine "Science" reports new investigations of the presumed place where the meteor fell, the Yucatán in Mexico. This crater, which previously was estimated to have a diameter of 175 km (one hundred seventy-five kilometers), is 300 km (three hundred kilometers), according to new analyses, making it almost as big as Belgium.

This renders more credible the theory of the following tsunamis, volcanic eruptions, forest fires, and dramatic climatic changes that killed (off) the dinosaurs. The Chicxulub crater is the largest in the internal solar system.

The crater was discovered only a few years ago because it was filled with deposits of limestone. Virgil Sharpton, a scientist at the Lunar and Planetary Institute in Houston, Texas, thinks that the crater was created by an explosion that was the equivalent to 100-300 (between one hundred and three hundred) million megatons of TNT.

He estimates that the explosion threw (up) into the atmosphere 200,000 (two hundred thousand) cubic kilometers of the earth that it collided with, which made the sun disappear for several months. This must have created a brief ice age, which eradicated the dinosaurs.

The theory of this great catastrophe was published in 1980 but was not universally accepted because no one had detected a crater large enough to possibly explain such an enormous natural catastrophe.
